@see https://bugs.documentfoundation.org/show_bug.cgi?id=136980 After I upgraded the package using apt, loowsd failed to start. lool@asuka:~$ /usr/bin/loolwsd --version --o:sys_template_path=/opt/lool/systemplate --o:child_root_path=/opt/lool/child-roots --o:file_server_root_path=/usr/share/loolwsd --pidfile=/var/run/loolwsd/loolwsd.pid loolforkit version details: 6.4.0 - e520aaa Neither /opt/collaboraoffice6.4/program/libsofficeapp.so or /opt/collaboraoffice6.4/program/libmergedlo.so exist. Failed to preinit lokit.
/opt/collaboraoffice6.4 is empty... Last upgrades are totally broken.
I retrieved /opt/collaboraoffice6.4/ after hard work and loolwsd now starts.
That's strange, because /opt/collaboraoffice6.4/program/libmergedlo.so is in package collaboraofficebasis6.4-core, which is installed if you install package loolwsd.
